Bail for spinning reel

ABSTRACT

A bail assembly is provided for a spinning reel of the type having a spool mounted for reciprocal and rotational movement with respect to a body, a drag system, a rotor with a line pickup generally surrounding the spool, and a handle drive mechanism for reciprocating the spool and rotating the rotor thereabout to wind line onto the spool. The bail assembly has a bail wire formed of spring tempered stainless steel wire stock and is bent in an arc with first and second ends respectively attached to the rotor by generally diametrically opposed first and second end mounts. The arcuate bail wire exerts spring tension and the end mounts are cooperatively configured so that the bail wire is manipulable in spring toggle motion from an open position permitting line to play freely off the spool to a closed position directing line to the line pickup for collecting line on the spool. The arcuate bail wire also biases the bail assembly to remain in one of the open and closed positions until manipulated to the other position.

FIELD OF INVENTION

The invention herein relates to a bail for a spinning reel wherein thebail wire provides spring tension biasing the bail wire to an open orclosed position.

BACKGROUND OF INVENTION

Spinning reels are a popular type of fishing reel, and are especiallywell adapted for casting lures and bait. A spinning reel generallycomprises a body and a leg for mounting the spinning wheel to a fishingrod. A spool is mounted for reciprocal and rotational movement withrespect to the body, and a drag system for the spool for controls therelease of line. A rotor with a line pickup generally surrounds thespool, and a handle drive mechanism reciprocates the spool and rotatesthe rotor thereabout to wind line from the line pickup onto the spool.The spool holding the line is oriented along the rod, so that line playsoff the spool freely during casting without need to rotate the spool inorder to release line.

To retrieve line, or to release line by rotation of the spool againstthe drag system, line is positioned on a line pickup mounted to therotor. In retrieving line, the rotor is rotated by the handle drivemechanism.

Line can be positioned on the line pickup in one of two ways. First, theline pickup can be fixed on the rotor generally over the spool, and thefisherman then uses a finger to place the line on the line pickup.

Line may also be positioned on the line pickup by a bail assembly. Thebail assembly generally includes a bail wire that extends across therotor and pivots between an open position and a closed position. In theopen position, the bail does not interfere with line playing off thespool during casting. In the closed position, the bail wire catches theline and directs it onto the line pickup.

A requirement of a bail assembly is that there must be a force thatkeeps it firmly in the closed position or firmly in the open position.It must remain open during casting, so that line plays freely off thespool. It must remain closed during line retrieval or line play offagainst the drag system, so that the line is controlled as desired. Inpresently know bail assemblies, this force is provided by one or morecoil springs acting on the bail wire through connecting members. Thecoil spring and its connecting members are generally positioned in apocket or housing positioned on the rotor, which creates a relativelybulky structure. The springs are prone to failure, from rust, saltwatercorrosion or simply breakage, and often have insufficient force toprevent the bail from closing as a result of casting motion.

Therefore, an improvement in bail mechanisms would be a welcome advancein the art.

SUMMARY OF THE INVENTION

It is a principal object of the invention herein to provide an improvedbail assembly for spinning reels.

It is an additional object of the invention herein to provide a bail fora spinning reel with high reliability.

It is also an object of the invention herein to provide a bail withsimplicity of construction and light weight, in part achieved through aminimum of moving parts.

It is a further object of the invention herein to provide a bail thatsmoothly guides line onto a line pickup of the spinning reel.

In carrying out the invention herein, a bail assembly is provided for aspinning reel of the type having a body and leg, a spool mounted forreciprocal and rotational movement with respect to the body, a dragsystem for the spool, a rotor with a line pickup generally surroundingthe spool, and a handle drive mechanism for reciprocating the spool androtating the rotor thereabout to wind line from the line pickup onto thespool. The bail assembly for use with the spinning reel has an arcuatebail wire formed of spring tempered steel wire stock, the arcuate bailwire having first and second ends respectively pivotally attached to therotor at generally diametrically opposed first and second end mounts.The bail wire is formed in an arc that creates spring tension, and theend mounts are configured such that the bail wire is manipulable inspring toggle motion utilizing the spring tension of the bail wire, froman open position permitting line to play off freely from the spool to aclosed position directing line to the line pickup for collecting line onthe spool.

In certain aspects of the invention, the end mounts are positioned andconfigured such that the bail wire spring tension toggles the bail wireat the approximate mid-point of movement between the open and closedbail positions, wherein as the bail wire moves from the mid-point, thespring tension biases the bail wire to the closest one of the open andclosed bail positions. Stops are provided to establish the opened andclosed positions.

In another aspect of the invention, the first end of the bail wire isattached to a first end mount at a fixed position on the rotor and thesecond end of the bail wire is attached to a bail arm, the bail armbeing pivotally mounted to the rotor for pivoting movement about a bailarm pivot axis, the fixed position of the first end mount being offsetfrom the bail arm pivot axis. The first end mount is offset below thebail arm pivot axis, such that the bail wire exerts increased springtension on the mid-point of the transition between the open and closedbail wire positions, thereby causing the toggle motion.

In an additional aspect of the inventions, both end mounts accommodateand control positions of the bail wire that cause toggle motion as thebail wire is moved between its open and closed positions.

Other aspects of the invention include low friction end mounts for theends of the arcuate bail wire. A fixed low friction end mount is a hardpolymer ball secured to the end of the bail wire and received andretained in a socket in the rotor. For an end mount including an arm,the arm is mounted to the rotor on low friction bearings, such as ballbearings.

In another aspect of the invention, one of the end mounts includes abail arm and the line pickup of the rotor is mounted on the bail arm. Anend of the bail wire is attached to the bail arm by a guide that directsline from the bail wire to the line pickup. The guide may have agenerally conical shape.

The foregoing and other objects and features of the invention hereinwill in part appear in the following detailed description of theinvention and the claims, taken together with the drawings.

DETAILED DESCRIPTION

With reference to FIG. 1, a spinning reel 10 having a bail assembly 12according to the invention herein is illustrated. The spinning reel 10generally comprises a body 14 having a mounting leg 16 extendingtherefrom, a spool 18 mounted for reciprocal and rotational movementwith respect to the body 14 and a drag system 19 for the spool. A rotor20 generally surrounds the spool 18, and a handle drive mechanism 22including a handle 24 and internal gearing, not shown but well known inthe art, reciprocates the spool and rotates the rotor 20 thereabout towind line onto the spool. The bail assembly 12 is mounted to the rotor20.

Several bail assemblies are described herein, and a second bail assembly30 is illustrated in FIGS. 2-13. The bail assembly 30 is characterizedby a bail wire 32, which is formed of spring tempered stainless steelwire stock. The bail wire 32 is bent into an arc, which develops springtension and provides the energy to assist in toggling the bail wire fromthe closed position shown in FIGS. 2-7 to the open position in FIGS.8-11 and for retaining the bail wire 32 in the appropriate position onceit is moved to one of the open and closed positions.

The rotor 20 has opposed extending walls 34 and 36 which generallysurround the spool 18 in the reel 10. The bail assembly 30 is mounted tothe rotor 20 on the walls 34, 36. The bail wire 32 is arcuate, and has afirst end 40 and a second end 42. The first end 40 is mounted to therotor wall 34 at end mount 41, which in the embodiment shown includes acounterweight arm 44, which is in turn mounted to the rotor wall 34 by ascrew 45. The first end 40 of the bail wire 32 has a stub axle 46 whichextends into the counterweight arm 44, wherein the pivot point of thefirst end 40 of the bail wire 12 is offset from the screw 44. It isimportant that the bail assembly 12 pivot freely, and therefore the stubaxle 46 is received in a polymer bearing 48, shown in FIG. 12, andreceived in a mating socket in the counterweight arm 44.

The second end 42 of the bail wire 32 is mounted to rotor wall 36 bybail arm 50. The bail arm 50 is rotatably mounted to the rotor wall 36about axis 52, seen in FIG. 5, being secured by a screw 54. The screw 54is diametrically opposed from the screw 45 mounting the counterweightarm 44, and the axis 52 passes through both screws 45 and 54. Thus itcan be seen that the mounting point of the first end 40 of the bail wire32 is offset from the axis of rotation of the bail arm 50. The secondend 42 of the bail wire 32 is mounted to the outer end of the bail arm50 by a conical guide member 60. The second end 42 of the bail wire 32extends into the conical guide member 60, and the guide member 60 issecured to the bail arm 50. A line pickup 58 is also mounted at the endof the bail arm 50, and the conical guide member 60 guides line capturedby the bail wire 32 onto the line pickup 58 when the bail assembly 12 isclosed. The line pickup 58 is preferably a line roller with bearings,for low friction.

Before the bail wire 32 is attached to the bail arm and counterweight,the first and second ends 40, 42 are closer together. In other words, inuntensioned condition, the bail wire 32 would define an arc of a smallerradius than when it is installed, and the bail wire 32 is thereforetensioned when installed to provide a force between the ends 40 and 42.If the ends 40, 42 are further spread apart during operation of the bailassembly 12, the tension and force increase. As the bail wire 32 istransitioned from the closed position shown in FIGS. 2-5 to the openposition shown in FIGS. 8-11, the bail arm 50 rotates about itsrotational axis 52. The configuration of the end mounts 41, 43 of thebail wire 32, including the bail arm 50, cause the first and second ends40, 42 of the bail wire 32 to separate during the transition with thegreatest point of separation occurring at or near the mid-point of thetransition from open to closed position. This creates a toggle function,such that when the bail is incrementally directed toward either of theopen or closed positions, the spring force drives the bail wire to thatposition and maintains it there.

It is important that the end mounts 41, 43 of the bail wire 32 rotatewith minimal friction. With reference to FIG. 12, end mount 41 is shown.The first end 40 of bail wire 32 has a stub axle 46 received in apolymer ball 64. The polymer ball 64 is received in socket 66 in thecounterweight arm 44, where it rotates with minimal friction. A clip 68secures the stub axle, polymer ball and bail wire 32.

The bail wire 32 is offset at the position established by the polymerball pivot point such that the toggle point favors the closed direction.This will make it more difficult to close the bail and easier to openthe bail. It is preferred that the bail is more difficult to closebecause the force from the casting out can prematurely close the bail.This bail design helps prevent this problem by the two directionaloffset position of the bail wire 32 at the polymer ball pivot point.

With reference to FIG. 13, the bail arm 50 of end mount 43 is mounted tothe rotor wall 36 by bearings 70 on bearing post 72. An O-seal 74 isalso provided. Ball bearings, roller bearings or other low frictionmounting may be used.

The open and closed positions of the bail assembly 12 are established bya pin 62 extending from rotor wall 36 adjacent the axis of rotation 52of the bail arm 50, and the bail arm 50 has an arcuate slot in which thepin 62 travels. The pin 62 engages against one end of the slot toestablish the open position of the bail assembly 12, and against theother end of the slot to establish the closed position of the bail.

In actual operation of the spinning reel 10 and bail assembly 12, thefisherman will grasp the bail wire 32 and move it from its presentposition, which may be open or closed, to its other position. As thebail wire 32 crosses the center point, i.e., the point at which thecompressive force of the spring is greatest, the bail wire 32 exhibitsits toggle function and will continue its transition to the desiredposition without further input from the user.

With reference to FIGS. 14-22, bail assembly 80 according to theinvention herein is illustrated. It is also the bail assembly shown onreel 10 in FIG. 1. In bail assembly 80, a bail wire 82 has first end 84and second end 86, which are respectively secured to first and secondend mounts 88 and 90. The first end mount 88 is a rotatable lever arm92, with an axis of rotation 94 extending through its mounting screw 96.The axis of rotation 94 also extends through end mount 90. The first end84 of the bail wire 82 is rotatably mounted to the lever arm 92, offsetfrom the axis of rotation of the lever arm 92.

The second end mount 90 is a bail arm 100, having its first endrotatably mounted to rotor wall 36 on the same axis of rotation 92 ofthe lever arm 92. The second end 86 of the bail wire 82 is secured tothe distal end of the bail arm 100, such that the bail wire 82 feedsline onto the line pickup 58 at the end of the bail arm.

The bail wire 82 is also spring tempered stainless steel stock bent toan arcuate shape and has a larger diameter when free of the end mounts88, 90 than when it is secured to the end mounts. Therefore, the mountedbail wire 82 is under tension that tends to pull on the lever arm 92.

The lever arm 92 has an arcuate slot therein which cooperates with a pin102 extending from the rotor wall 34 to establish open and closedpositions of end mount 88 of the bail assembly 80. In the closedposition shown in FIGS. 14, 15 and 18, the bail wire pulls on the lever92, maintaining it against the pin 102 in the closed bail condition. Asshown in FIG. 19, as the bail assembly 80 is moved from the closedposition toward the opened position, the configuration of the end mounts88, 90 increases the spring tension in the bail wire 82, and as the bailwire 82 reaches the center point, the lever arm 92 begins to rotate. Therotation is shown continuing in FIG. 20, after the bail wire 82 haspassed over center, and is complete in FIG. 21, where the bail assembly80 is shown in its open position. When the bail is returned to itsclosed position, the sequence of motion illustrated in FIGS. 18-21 isreversed. Therefore, the toggle function of the bail assembly 80 isexpressed in the toggle action of the lever arm 92. This is anotherexample of an end mount configuration that utilizes spring tension ofthe bail wire to toggle the bail assembly between its open and closedpositions.

FIGS. 22-25 illustrate another bail assembly 110, which may be used withthe spinning reel 10 of FIG. 1. The bail assembly 110 is mounted to arotor 20 a having rotor walls 34 a and 36 at end mounts 112 and 114. Endmount 114 includes a bail arm 100 and line pickup 58 as described abovewith respect to bail assembly 80 is wall 36 and receives end 118 of bailwire 120. The second end 116 of the bail wire 120 is received in a slot122 in the rotor wall 34 a, which functions as the end mount 112. Theslot 122 is elongated, and has stop indents 126 and 128 at its oppositeends.

The second end 118 of the bail wire 120 that is received in the slot 122is fitted with a small roller bearing or the like, to reduce friction inthe slot 122 as the end 118 of the bail wire 120 moves in the slot 122between indents 126, 128.

FIGS. 22-25 illustrate the progression of the bail assembly 110 whenmoved from its closed position in FIG. 22 to its open position shown inFIG. 25. In the closed position shown in FIG. 22, the end 116 of thebail wire 110 is in detent 126 of the slot 120. The bail assembly 110 ismanipulated to its open position by lifting the bail wire 120. As shownin FIG. 23, as the bail wire 110 is initially pushed and lifted towardthe open position, end 116 of the bail wire 120 moves from detent 128toward detent 126. As the bail wire 120 goes over center, which is theposition generally shown in FIG. 24, the bail assembly 110 toggles tothe open position shown in FIG. 25 with the end 116 of the bail wire 120at the second detent 128 of the slot 122. Again, moving the bailassembly 110 from the open to the closed position is achieved by reversemanipulation. The slot 122 provides an end mount 112 for the tensionedbail wire 120 in a configuration that achieves toggle action of the bailassembly 110 from its closed to open position and from its open to itsclosed.

Accordingly, bail assemblies for spinning reels have been describedwhich admirably achieve the objects of the invention herein. It will beappreciated by those skilled in the art that the foregoing embodimentsare illustrative only, and that various changes may be made withoutdeparting from the spirit and scope of the invention.
